Late today president Obama warning Iraq they need to come up with a political solution themselves. This evening we're seeing the view from an American f-18 military operation still under way to support humanitarian aid and air strikes there. There's a lot of concerns about Americans on the ground in erbil, Iraq. For the first time we're getting a true picture of the nightmare, thousands of refugees are facing as they hide in the mountains.
